a percentage it is z*·√(p(1 − p) / n), where p is the sample proportion, n the sample size and z* the critical value for your confidence level (1.96 for 95%).

To halve that margin you would need roughly four times the sample. To halve that margin you would need roughly four times the sample.Worked example: with 1,000 respondents split 50/50 at 95% confidence, the margin is 1.96 × √(0.5 × 0.5 ÷ 1000) ≈ 0.0158 ≈ 3.1 percentage points.To halve that margin you would need roughly four times the sample.Worked example: with 1,000 respondents split 50/50 at 95% confidence, the margin is 1.96 × √(0.5 × 0.5 ÷ 1000) ≈ 0.0158 ≈ 3.1 percentage points.To halve that margin you would need roughly four times the sample.Worked example: with 1,000 respondents split 50/50 at 95% confidence, the margin is 1.96 × √(0.5 × 0.5 ÷ 1000) ≈ 0.0158 ≈ 3.1 percentage points.To halve that margin you would need roughly four times the sample.Worked example: with 1,000 respondents split 50/50 at 95% confidence, the margin is 1.96 × √(0.5 × 0.5 ÷ 1000) ≈ 0.0158 ≈ 3.1 percentage points.Worked example: with 1,000 respondents split 50/50 at 95% confidence, the margin is 1.96 × √(0.5 ×
